I have bougt a power fc of a guy on here and want to plug it in just want to know is there anything i need to do or be carefull with?

Thanks again.

...disconnect the battery, reset the unit with a commander and don\'t run it on whatever map is on there as will probably be a different setup and may damage your engine
